One of the boldest dreams in modern astronomy is the search for Earth-like worlds beyond our solar system. These exoplanets may hold oceans, rocky ground, and even atmospheres rich in oxygen or ...

If Earth-like planets require an extremely rare supernova encounter, then water-depleted rocky planets might be exceptional. But if cosmic-ray immersion is sufficient—and common—then the conditions ...
